Description

Application

• MOPS buffer for enhancing photoacoustic imaging: A study explored the utility of MOPS buffer in the synthesis of gold nanostars, enhancing their application in photoacoustic imaging due to the buffer′s pH stability, which is crucial for maintaining the optimal reaction conditions necessary for controlled nanostar growth (Zhang et al., 2024).


• MOPS for intracytoplasmic sperm injection (ICSI): MOPS buffer′s role was investigated in a study where its influx following membrane piercing during ICSI was found to alter the transcriptome of human oocytes, suggesting a significant impact on oocyte viability and fertilization outcomes (Mendola et al., 2024).


• Stability studies with MOPS in zinc complex formation: Utilizing MOPS buffer, a study examined the structures, solution equilibria, and speciation of zinc complexes with chloroquine and hydroxychloroquine, underlining the buffer′s role in maintaining the integrity and stability of these complexes (Squarcina et al., 2024).


• MOPS in radiolabeling and in vivo evaluation: MOPS buffer was integral in the radiolabeling processes of lanmodulin with biomedically relevant lanthanide isotopes, enhancing the precision and effectiveness of in vivo evaluations in biomedical research (Martin et al., 2023).
